[PULL 1/2] block/export/fuse.c: fix musl build |
Date: |
Mon, 9 Aug 2021 19:03:18 +0200 |
From: Fabrice Fontaine <fontaine.fabrice@gmail.com>
Fix the following build failure on musl raised since version 6.0.0 and
https://gitlab.com/qemu-project/qemu/-/commit/4ca37a96a75aafe7a37ba51ab1912b09b7190a6b
because musl does not define FALLOC_FL_ZERO_RANGE:
../block/export/fuse.c: In function 'fuse_fallocate':
../block/export/fuse.c:563:23: error: 'FALLOC_FL_ZERO_RANGE' undeclared (first
use in this function)
563 | } else if (mode & FALLOC_FL_ZERO_RANGE) {
| ^~~~~~~~~~~~~~~~~~~~
